Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a product transport device that stores arbitrary products in trays in various factories and transports and connects them between various manufacturing and processing lines.

In order to automate the manufacturing and processing of small products in various factories, etc., it is necessary to transport the products between the various manufacturing and processing lines in an automatically organized and regulated state.

This transportation system generally transports small products by storing them in trays, which are flat containers, and then supplies these trays to the product loading and unloading sections of each manufacturing and processing department using an automated system such as a conveyor. However, automated systems such as conveyors have the disadvantage that the equipment is large and cannot be easily installed, and it is also difficult to supply each tray to the product loading/unloading area with accurate positioning. There were drawbacks. Moreover, in order to sort and transport the large number of trays on which the products have been loaded and unloaded, automatic product transport is not possible unless the large conveyor system is used.

The present invention has been made in view of the above-mentioned points, and when transporting products using trays, a large number of trays are housed in a transport body within the main body of the device, and the trays are moved from any stacked shelf within the main body. By installing a work device that can be loaded and unloaded in the product loading/unloading section of a manufacturing/processing department for various products, it is possible to easily continuously supply trays to the product loading/unloading section with a simple device. At the same time, it is possible to supply each tray with accurate positioning to the product loading/unloading section, and furthermore, each tray after loading and unloading the product is stored in a stacked state within the transport body. and
To provide a product conveyance device that allows the next conveyance work to be carried out in an organized manner.

At this time, the carrier 1 is operated to take out and take out each of the stacked trays 2 from an arbitrary shelf section by the operating device 5, and the work robot 40 is It is configured such that products are always loaded and unloaded at a predetermined position on a tray 2 pulled out from an arbitrary shelf part of a body 1.

FIG. 2 is a perspective view of the L-ray conveyor. In the embodiment (the general conveyance body 1 is made up of eight stacked trays 2, the stacked shelves can be arbitrarily selected in proportion to the size of the working device 10. In the figure, the conveyance body 1 is The trays 11 each having an opening 12 on the side surface are arranged vertically in eight consecutive stages, and the tray 2 is stored in each of the shelves 11, 11 so as to be freely put in and taken out through the opening 12. Although the trays 2 are vertically stacked, there is no contact between the adjacent upper and lower parts, so that they can be freely taken out and inserted through the opening 12. Each working part 50A,
50B are conveyed and connected. The carrier 1 is transported by an arbitrary trolley or the like. It is sufficient to have at least one working section 50A, and this working section 50A may be connected to a general working section or a subcontracted factory outside the same factory using the conveyor 1.

The tray 2 described above is formed as a flat rectangular container with an open top surface, as shown in FIG. Note that the external shape and depth of the tray can be freely selected, and any tray such as a general pallet or a commercially available plastic container can be used. A formwork 17 having a product fitting part 18 made of styrofoam or the like adapted to the outer shape of the transported product is stored in the broken tray so that the product itself can be positioned. 40 can be performed more automatically. Also,
The mold 17 and the tray 2 themselves can also be integrally molded with any material.

Next, a description will be given of the working device 10, which includes the device main body 3, the tray mounting section 4, and the tray operating device 5.

The working device 10 is installed near a working section 50 in various factories, etc., and as shown in FIGS. 4 and 5, the device main body 3 is formed entirely of a rectangular box. A tray mounting section 4 consisting of a space in which the tray transport body 1 is housed is provided within the box-shaped apparatus main body 3, and the tray mounting section 4
A tray operating device 5 is provided in the apparatus main body 3 facing the tray.

The carrier 1 of the tray 2 is usually placed on an arbitrary trolley, and the mounting portion 4 of the working device 10 is transferred from this trolley.
It will be moved and placed on. On the other hand, the above-mentioned carrier may be moved and placed on the mounting section 4 together with a trolley, or may be transported by an automatic machine such as a fork without using a trolley.

As shown in FIGS. 1 and 4, the tray mounting section 4 has a C-space section into which the carrier 1 of the tray 2 is detachably mounted, and this space is open on the side. Transporter 1
Attach by sliding it from the side.

The operating device 5 for the tray 2 provided in the apparatus main body 3 basically comprises a tray 2 loading/unloading device 6 and an elevator 7. The entrance/exit machine 6 and the elevator 7 each operate according to commands from the control unit 30.

Next, the loading/unloading machine 6 that constitutes the tray handling machine 5 is configured by installing a hook-shaped metal fitting on a cylinder having a stroke that can cross-feed one tray 2. As shown in FIGS. 5 and 6, the stacked trays 2 are taken out from a specific shelf 11 and moved laterally.

To take out the tray 2, place the tray 2 on the top surface of the elevator 7.
It is done by placing the . The elevator 7 is configured with a folding arm provided on the lower surface of the base 9, and moves up and down adjacent to the mounting section 4 between its upper and lower portions. In the embodiment, the base 9 is designed to accommodate and place two trays 2 in a non-contact manner.

The elevator 7 with the tray 2 placed on the base 9 is located at the product entrance/exit section 1
4 and transfer the tray 2 to the product entrance/exit section 14 using the cross-transfer tool 13. At the product entrance/exit section 14, the tray 2 is loaded and unloaded with products by a work robot 40.

The lateral feeder 13 is constituted by a cylinder mechanism substantially similar to the loading/unloading machine 6. However, the loading/unloading machine 6 is configured to have a lifting function to move up and down according to the vertical position of each tray 2.2.

Since the base 9 of the elevator 7 can accommodate two trays 2, as shown in FIGS. , by interlockingly lowering one tray and moving it to the two-metal product entrance/exit section 14 of one of the trays that had been stored in advance.
The speed of work is achieved by preventing the work robot 40 from waiting for work. The elevator 7 then descends, stores the processed tray 2 on the specific shelf 11, stores the next tray 2, and ascends again to the product entrance/exit section 14 as described above.

In addition, the apparatus main body 3 in the above embodiment stores one spare tray 2 in addition to the tray 2 in the carrier 1, so that all the trays 2 in the carrier 1 (eight in the embodiment) ) has finished loading and unloading products in the − cycle and while the spare tray 2 is loading and unloading products, the carrier 1
This is intended to improve work efficiency by allowing the replacement work to be performed from the mounting part 4.

Next, the operation of the above-mentioned working device 10 will be explained.

First, the carrier 1 in which trays 2.2 for loading and unloading products are stacked and stored is made to correspond to the work device 10vc installed in a specific work section 50, and the carrier 1 is pushed into the mounting section 4. Installing.

Next, each operating section operates as follows based on commands from the control section 30. That is, the elevator 7 and the loading/unloading machine 6 move to the front of the tray 2 to be taken out in the carrier 1 mounted on the loading section 4, and the loading/unloading machine 6 pulls out the tray 2 onto the elevator 7 and places it thereon. Next, the elevator 7 transfers the tray 2 to the product entrance/exit section 14, and the work robot 40 loads and unloads the tray 2 with products. The tray 2 that has been worked on is similarly returned to the empty shelf 11 of the carrier 1 by the elevator 7 and the loading/unloading machine 6, completing one cycle of product loading and unloading work. This work can be performed on all trays 2 of the conveyor 1 in order, or on only one particular tray 2.

Therefore, when loading and unloading products on all the trays 2, it is possible to repeat the above operation for the number of trays 2 on the transport body 1, so that all the trays 1y-2, 2 attached to the attachment section 4 can be loaded and unloaded. On the other hand, they carry out the work of loading and unloading products. In other words, when eight empty box-like trays are installed, by taking out and putting in and taking out all the empty boxes in order, products are loaded into each and stored in eight layers in the conveyor 1, while products are loaded and stored in eight layers. The work is completed by stacking and storing empty box-shaped trays 2, 2 after unloading the products from each tray 2 on the carrier 1 of a certain tray 2. After the above-mentioned work is completed, the carrier 1 is taken out from the mounting section 4, and then a new carrier 1 is mounted on the mounting section 4.

Furthermore, the work of loading and unloading products can also be performed manually without using the work robot 40. In addition,
The elevator 7 may be any device as long as it has the function of substantially raising and lowering the tray 2, and may be configured by, for example, a combination of a cylinder and a base, an air spring, or the like.

Next, FIG. 7 shows another embodiment. In the figure, the elevator 7 is provided on the lower surface of the mounting portion 4 at a distance τ. However, the elevator 7 lifts and lowers the tray 2 in the loading section 4 along with the carrier 1, and stops so that the tray 2 to be taken out corresponds to the product entrance/exit section 14, and then the tray 2 is moved to the product entrance/exit section 14 by the loading/unloading machine 61C. It becomes like taking it out.

Incidentally, since it is possible to take out only arbitrary trays 2 of the conveyor 1, the present conveyor 1 can also be used as a storage for managing gold parts and the like.

As described above, the product conveyance device of the present invention has a working device in which a conveying body containing a large number of stacked trays is removably installed in the product loading/unloading section. Each stacked tray is taken out one by one to the product entrance/exit section, making it easy to continuously supply trays to the product loading/unloading section with a simple device. Since the trays are taken out by the operating device of the work equipment, trays can be fed with accurate positioning.Furthermore, the trays can be taken out from any shelf of the conveyor, and after loading and unloading the products, the trays can be fed with precise positioning. Since the items are returned to the shelf and stacked and stored on the conveyor, the next conveyance operation can be carried out in an organized manner. Furthermore, there is also the effect of using the carrier as a stocker.
